Design Submission & Internal Review Gate

Last Updated June 2026

Purpose

After a designer submits work, it passes through an internal review before reaching the customer. Today Anmol reviews everything. This spec encodes his review logic as automated checks so standard jobs go to RM/Anupam, and Anmol only sees high-value or flagged exceptions.

Key note: Reviewer sees the original WhatsApp/email message alongside the AI brief and submitted design — not just the formatted summary.

Actors

Actor	Type	Role
AI Review Engine	System	Runs automated checks immediately on submission
RM	Internal	Reviews Coral submissions against checklist
Anupam	Internal	Reviews CAD submissions
Anmol	Internal	Reviews only: high-value, flagged, or revision-loop jobs

Trigger

Job state = COREL_SUBMITTED or CAD_SUBMITTED

Full Flow

1. Submission received
2. AI Review Engine runs all automated checks (see below)
3. Compute result:
   PASS → route to RM (Coral) or Anupam (CAD) for checklist review
   FAIL → route directly to Anmol with flagged reasons
   WARN → route to RM/Anupam with warnings visible
4. Reviewer opens job review screen:
   → Original customer message (raw WhatsApp text + images)
   → AI parsed brief
   → Submitted design (render / CAD preview)
   → AI auto-check results per item
   → Review checklist — must tick every item
   → Pricing auto-calculation already shown
5. Reviewer completes checklist + adds notes
6. Decision:
   APPROVE → state = CAD_INTERNAL_QC | next state
             → goes to pricing → then to client
   SEND BACK → state = COREL_QUEUED | CAD_QUEUED
              → revision note sent to designer
              → revision count++
7. If value > threshold OR revision_count >= 3 → auto-escalate to Anmol

AI Auto-Checks

Check	Logic	Result
Weight in budget range	gold cost vs brief.budget_usd	WARN if >15% over, FAIL if >30%
Diamonds in budget range	diamond cost at client rate vs remaining budget	WARN / FAIL
CAD file valid	.3dm parseable, not corrupted	FAIL
Render present	Render image uploaded with CAD	FAIL
Weight report present	PDF or text included	WARN
Ring size present	sub_category=ring AND no size in brief	WARN
Revision count	revision_count >= 3	FLAG to Anmol

Review Checklist

Coral

Layout matches reference / description
Font appropriate for customer (if text/nameplate)
Diamond coverage fits stated setting
Approx carat weight reasonable for budget
No missing elements (bail, clasp, chain attachment)
Customer recurring instructions followed

CAD (above plus)

Gold weight within ±15% of budget estimate
Diamond carat within ±15% of budget estimate
Ring/bracelet size matches brief
Wall thickness adequate (AI check passed)
Prong structure fits stone size
Finding type matches brief
Internal finish noted (e.g. polished inside band)

Escalation to Anmol

Trigger	Reason
AI check = FAIL on weight/diamond	Risk of wrong pricing on high-value piece
value_estimate > $15,000	High-value threshold
revision_count >= 3	Revision loop — needs senior review
Reviewer explicitly escalates	"Send to Anmol" option on review screen
New customer (first 3 orders)	Build trust before delegating

Revision Flow

Reviewer must select reason(s) when sending back:

Weight too high / too low
Diamond coverage incorrect
Wrong font / style
Missing element
Dimension mismatch
Customer instruction not followed
Other (free text required)

Designer gets notification with specific reasons. Job appears at top of their queue (revision jobs priority-boosted).

Business Rules

Rule	Detail
Checklist mandatory	Cannot approve without ticking every item
Revision reason mandatory	Cannot send back without selecting at least one
Anmol sees L2+ only	Standard passing jobs never appear in his queue
SLA for review	4h. Escalate to Anupam (CAD) or team lead after 4h.
Spec lock on approval	Once approved here, spec frozen until client approves.
